I will build your custom trading tool, dashboard or training app in python
AI Automation Developer, Markets and Data
Hi, I'm Timon — a full-stack developer and algorithmic trader who builds things that actually run in production. I develop MetaTrader 5 Expert Advisors (MQL5) and TradingView Pine Script strategies, a...
About this Gig
I build the tools I use myself and one of them is fully open source, so you can read the code before you hire me.
I develop trading tools that turn raw data into something you can act on: dashboards, journals, analysis apps, and training tools that let you practise on historical sessions instead of your live account.
What I build:
Dashboards and performance journals with real statistics
Data pipelines: tick and bar data into a clean local store
Analysis apps with charts, filters and outcome statistics
Training tools: replay a session, make your call, get scored against what actually happened
Custom desktop apps for your own workflow
Stack: Python (FastAPI, pandas, numpy), React/TypeScript, SQL, desktop packaging. Everything runs on your machine by default no cloud lock-in, your data stays with you.
Why me: I trade my own systems live and publish tools on TradingView and the MQL5 Market. One of my complete applications a four-view market analysis studio built on 13 years of data is public and open source. Ask me and I'll show you the code.
Tell me what you want to see or measure, and I'll tell you what is realistic before you order.

FAQ
Can I see something you built?
Yes. One of my complete tools is public and open source, including the full source code and screenshots. Message me and I'll point you to it.
Do I need to provide the data?
Either works. If you have data, I'll build around it. If not, I set up a pipeline that fetches and stores it. I'll tell you which is cheaper for your case before you order.
Does it run in the cloud?
By default everything runs locally on your machine, so your data and your analysis stay with you. Cloud deployment is possible if you want it.
Do I get the source code?
That is one of my specialities: replaying historical sessions, hiding the outcome, scoring your call against what actually happened, and tracking your hit rate against the base rate rather than against 50%.
Can you add training or practice features?
That is one of my specialities: replaying historical sessions, hiding the outcome, scoring your call against what actually happened, and tracking your hit rate against the base rate rather than against 50%.
Can you rebuild a tool I saw somewhere?
I can build something that does the same job. I do not copy someone else's code or a licensed product.
Which markets and data formats do you work with?
Indices, FX, metals and commodities, from 1-minute bars upward. Common formats: CSV, parquet, SQL, broker exports and public APIs.
